I have been with Zen Internet for 4 years now. Since my first nightmare with BT when broadband started taking off in the UK, I never went for a big name broadband supplier again. Was with Demon for a while and their foreign support helpdesk was pathetic when something went wrong. Went to Zen for business and residential broadband thinking any company offering a 1 month rolling contract must have high standards and so far I have been proven correct. Zen might be more expensive and less value than some other ISPs but you get what you pay for with Zen. Customer service actually knows what is going on with orders and technical side of things. Super friendly. I thought the usage cap might be an issue but in 4 years it never has been. Highly recommended with support and company based in the UK.
